Formula:
D3[Si2O5](OH)4 D= Mg, Fe, Ni, Mn, Al, Zn
Name:
First described from Yaberg Sweden, in 1808. Often considered a variety of antigorite, but picrolite from Taberg was later found to be carlosturanite, and it seems that other picrolite specimens can be other species of serpentine, including lizardite and chrysotile.
A variety of Serpentine Subgroup
Columnar or coarsely fibrous (non-asbestiform) variety of serpentine, commonly referred to as a variety of antigorite but may be other species.
